I'm afraid I have to blunder in again with a loud voice and a sweaty face and insist you remove the rest of the paint from the interior of that shell...lol but seriously though you're almost there. Not saying you'll get the ink but it's a way better feeling to not be putting paint over old paint. Another acetone-stinking hour maybe, a light sanding, Tommy's paint......and I accidentally knock over some furniture on the way out.Mitch
DTF!
Actually, BIN shellac primer/sealer is extremely THIN in viscosity. It is NOT a "high build" primer, thus all it will do is BLOCK the rest of that ink and not sit on top of the wood fiber clogging it with pigment, as he has already removed a good amount of the original paint with all his prep thus far. It will save removing any more of the wood by sanding, etc., and also supply an excellent base for the BM 333-02. However!... there are SO MANY ways to achieve an end, and most all of this is completely subjective to personal opinion and experience anyway!
